Idle sputter potential fuel pump failure

[blindside]

2004 TiAg with 125k mileage. Two weeks ago an engine sputter, almost to a stall, occurred on a cold start. It fluctuated between 500-1200 rpms and lasted until the engine reached running temp. It reoccurred yesterday. Same procedures and symptoms from the initial occurrence. For a third time this morning the sputter started up. I noticed that the fuel gauge started moving up and down as well. Not as drastically as the rpms but about an 1/8th tank fluctuation.

Initially, I thought it could be the fuel pump. I'm unsure from previous owners service records if a pump swap had been done. Ill do research soon but this just took place and I'd like some insight.

I'll have a video up once my engine has cooled.

I don't think it's the fuel pump. I would think its the disa.

I know the disa was replaced 15k ago so it doesn't seem likely it's disa

Can you get some codes read? Perhaps fuel filter?

ICV may be dirty as well.

Could clean your MAF for cheap.

+1 on ICV.

+1 on ICV.

+2

I had the same symptoms and after cleaning my icv they went away.

That's for the insight. I'll dive into that Tuesday and update.
